Abstract: A seat-belt retractor comprising a seat-belt spindle which is rotatably mounted in a housing, an electric motor for driving the seat-belt spindle, and a gear mechanism that transmits the rotational motion from the electric motor to the seat-belt spindle, wherein: the gear mechanism, when deactivated, can be driven as an assembly for driving the seat-belt spindle with a first torque; the seat-belt retractor has a first part, which, when a tensile force exerted by the seat-belt is exceeded, is driven in a rotational motion opposite to that of the rotational direction of the electric motor; and a braking device, which brakes the rotational motion of the first part, thereby actuating a blocking device blocking a second part of the gear mechanism, the blocking device activating the gear mechanism to transmit the rotational motion of the electric motor in a reduction ratio to the seat-belt spindle.

Abstract: The invention relates to a load-bearing seat belt retractor for a seat structure of a vehicle seat. The seat belt retractor has two housing halves, between which functional modules of the seat belt retractor are arranged. One functional module is a belt spool with a winding axis, wherein a plurality of support plates oriented perpendicularly to the winding axis is provided on the functional modules, each said support plate having at least two locking noses, and the locking noses engage into corresponding locking holes in the two housing halves. The housing halves have beads and/or reinforcements directed toward the functional modules, and at least one section of a functional module and/or a section of a support plate is supported against the beads and/or reinforcements in at least one direction parallel to the winding axis.

Abstract: The invention relates to a belt retractor surrounding a belt reel which is rotatably mounted in a frame, and comprising a force-limiting device with at least one plastically deformable first torsion rod, wherein the first torsion rod has a first end rotationally fixed to the belt reel and a second end rotationally fixed to a profiled head which can be blocked via a first blocking device in a fixed manner relative to the vehicle. The belt reel, the first torsion rod and the profiled head are arranged coaxially to one another and in series relative to one another.

Abstract: The invention relates to a load-bearing seatbelt retractor for a seat structure of a vehicle seat, the seatbelt retractor having two housing halves between which functional modules of the seatbelt retractor are disposed. One functional module is a belt reel having a winding axis. The two housing halves form two mutually parallel receptacles in the seatbelt retractor, which are oriented perpendicular to the winding axis. Two seat bars can be inserted into the receptacles. The two housing halves are in contact at least on two contact lines above and below the functional modules with respect to an insertion direction of the receptacles. The lower contact line splits open on both sides along the winding axis such that respective intermediate spaces open toward the receptacles are formed.
